Safety Information
PLEASE READ THIS MANUAL BEFORE INSTALLING AND USING FIREPLACE.
IMPORTANT: Read all instructions and warnings carefully before starting installation. Failure to
follow these instructions may result in a possible fi
re hazard and will void the warranty.
Description
The BR/BC Series fireplaces are solid fuel, woodburning
fireplaces. The BR36/42 (Builder Radiant) is a clean-face
fireplace and the BC36/42 (Builder Circulating) unit has
fixed grilles.
Precautions
CFM Corporation fireplaces and component parts have
been highly tested and will operate safely when installed
in accordance with instructions provided in this manual.
Carefully read and understand all instructions before
beginning installation.
If you notice any damage to fireplace or component parts,
immediately report damage to your Majestic Fireplaces
dealer.
Only use CFM Corporation components or the warranty
will be voided and a fire hazard may be created.
CFM Corporation warranty will be voided by and CFM
Corporation disclaims any responsibility for the following
actions:
• Installation by any other than a qualified install-
er, preferably NFI or WETT (Canada) certified.
• Installation of any damaged fireplace or chim-
ney component;
• Modification of fireplace, chimney assembly or
any component parts thereof; (except for chase
flashings as detailed in Chimney Top installation
instructions).
• Installation other than as instructed by CFM
Corporation; or
• Installation and/or use of any component part
not manufactured or approved by CFM Corporation in combination or assembly with a Majestic Fireplaces fireplace system, notwithstanding
any independent testing laboratory or other
third party approval of such component parts
or accessory.
Any such action may possibly cause a fire hazard.
Consult local building codes to ensure that you are in
compliance before installing the fireplace.
Fireplaces must be vented to the out-of-doors.
Do not obstruct or modify air inlets/outlets in any
manner.
Do not install combustible materials on any of the
black fireplace surround.
Burn only solid wood fuel or gas logs.
Do not install a solid fuel burning insert or other
products not specifi
ed for use with this fireplace.
Proposition 65 Warning: Fuels used in gas, wood-
burning or oil fired appliances, and the products of
combustion of such fuels, contain chemicals known to
the State of California to cause cancer, birth defects
and other reproductive harm.
California Health & Safety Code Sec. 25249.6
Drafts
The fireplace should not be located in areas that create
drafts (ie: frequently opened doors and central heating air
inlets/outlets) that hamper the normal flow of air into the
fire.
Gas Logs
If you plan to install a gas log, the gas line should be
installed before framing the fireplace. The gas line must
be installed by a certified gas line installer.

B. Do not use more than 4 elbows per

.
Attach the straps of the return (top)
elbow to a structural framing member
.

C. The chimney cannot be more than 30˚
(45˚ in Canada) from the vertical plane in
any installation*.
D. The maximum length of the angled run
of the total chimney system is 20 feet. (G
plus H cannot exceed 20 feet.)
E. A chimney support (Model SKCS8)
is required every 6 feet of angled run of
chimney
. Chimney supports are required
for every 30 feet and 60 feet (SK8 pipe)
or 20 feet and 40 feet (3-wall pipe) of vertical chimney height above the hearth.
Determine the of
fset distance of your
chimney arrangement from the centerline
of the fireplace to the centerline of the
chimney where it is to pass through the
first ceiling.
NOTE: This offset distance may not be
your full of
fset distance. See Examples 2
and 3.

Planning Information
The Ten Foot Rule
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a fire
safety rule and not a draft rule. To ensure proper draft,
it is recommended that you always meet or exceed the
“Ten Foot Rule,” especially when installing a termination
on a high pitch roof. (Fig. 8)
The key points of the "Ten Foot Rule" are:
1. If the horizontal distance from the chimney to the
peak of the roof is 10' (3m) or less, the top of the
chimney must be at least 2' (610mm) above the peak
of the roof, but never less than 3' (914mm) in height
above the highest point where it passes through the
roof.
2. If a horizontal distance from the chimney to the peak
of the roof is more than 10' (3m), a chimney height
reference point is established on the surface of the
roof a distance of 10' (3m) from the chimney in a
horizontal plane. The top of the chimney must be
at least 2' (610mm) above the reference point, but
never less than 3' (914mm) in height above the highest point where it passes through the roof.
Determine how the chimney will be run, length of run
and chimney components required to complete the
job. (Fig. 6) Never install a chimney below minimum
heights.
In planning a chimney system, it is important to know:
1.
The height of a chimney is measured from the
hearth to the exit point on the termination.
2. A chimney cannot be offset more than 30° from a
vertical plane.
3. A chimney may run straight up or it may be necessary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20' (6 m).
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extending more than 6' (1.8 m) above a roof line.

Reference
Point
Preplanning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and how the
chimney system will be run.
Mounting the Fireplace
A fireplace may only be mounted on the following surfaces:
1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath
each of the four (4) corners of the fireplace.
The fireplace must be spaced 1/2" (13mm) from a combustible back wall and 1/2" (13mm) from a combustible
side wall or support. (Page 14, Fig. 20)

Insulating Fireplace Enclosure
for Cold Climates
Installation
Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30' (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30' (9m) with SK8 chimneys or 20' (6m)
with 3-wall chimneys. Locate chimney supports at ceiling holes or other structural framing at 30' (9m) (SK8)
or 20' (6m) (3-wall) heights. Spacing between chimney
supports must not exceed 30' (9m) (SK8) or 20' (6m)
(3-wall). Use Chimney Support Model SKCS8. (NOTE:
The SKCS8 can not be mounted directly to the
fireplace.) Support provided by elbow straps fulfills the
support requirement only if they are spaced as previously described. (A chimney support is 2¹⁄₂" (64mm)
long when installed.)
Angled chimney runs require a support every 6' (1.8m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 9)
Chase Installation
A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. Chases are typically built
on the outside of the house with fireplace opening cut
into the outer wall of a room. (Page 5, Fig. 5)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Majestic Fireplaces dealer for assistance.
If you live in a cold climate, it is not required but
highly recommended that you insulate fireplace
enclosure to eliminate cold air penetration as much as
possible.
Insulate base of fireplace with a noncombustible
insulation rated for a minimum of 300°F
. Insulating
is very important for outside wall installations over
a concrete slab. If fireplace is installed on a platform,
insulation should be placed on top of the platform
before fireplace is set. (Fig. 10)
When a fireplace is installed in a chase or on a
outside wall, enclosure should be treated like any
outside wall in a home. Insulation should be installed
on the inside wall as well as the outside wall(s). In a
chase, it is also a good idea to install a firestop at the
first ceiling level above the fireplace and enclose the
chase with sheeting material. Insulation may then be
installed above sheeting material to assure the space
around the fireplace is totally protected. (Fig. 5)
When installing the chimney, DO NOT caulk between
outer pipe and firestop. It is vital that some air be allowed to flow through this very thin gap.
CAUTION: WHEN INSTALLING A FIREPLACE
IN AN INSULATED ENCLOSURE, BE SURE ALL
REQUIRED AIR SPACES ARE MAINTAINED. (Page
14, Figure 20)
